Description

Hyosung’s ProPAC II is designed with a focus on the reliability of system protection. Being optimized for power quality monitoring and designed for strong noise resistance, it prevents malfunction or non-operation of the equipment.

Features

Prevents malfunction or non-function
Dual protection function: protects a single feeder using two relays
Strong noise resistance
Shields electromagnetic waves: protects all sides with metal
EMC and EMI certification
Dual filter applied to remove measurement noise
Easily monitor CT and PT’s condition
Alarm sounds upon breakage or mal-wiring of CT or PT: uses 4CT and GPT wiring
Measures k-Factor and harmonics
Measures 2nd to 15th harmonics
Checks the waveform distortion and sag/swell using an oscilloscope function
Applicable to BAS (Building Automation System)
Supports BAS protocol: LonWorks, BACnet (optional)
Supports standard protocols - Modbus, DNP3.0
Additional protocol converter is not required
Uses 10/100Mbps Ethernet to support high-speed communication
Communication is available even when one channel fails
Dual communication channels may be used at the same time
Supports various languages (Korean, English, Chinese)
Enables swift reaction upon emergency and prevents inappropriate operation
Built-in alarm function
Additional alarming device unnecessary
Trip logic can be configured as desired by user
Sequence, such as inter-locking between relays or switchgears, may be implemented
